SELVAGE TRIMMING TEMPLE FOR Looms Filed March l0, v195'? 2 Shee'es--Sheeil 2 Patented June 13, 1939 inurl-:ov STATES PATENT OFFICE 2 Claims.

This invention relates to a loom temple and it is one object of the invention. to provide a temple adapted to be mounted upon the frame of a loom and carrying trimming mechanism, by

5 meansv of which the selvage of clothwoven in the loom may be trimmed and all threads removed therefrom as the woven goods passes through the loom.

Another object of the invention is to provide a temple which is carried by a stationary portion of the frame of the loom instead of being carried by the breast beam of the loom, thus providing a temple which remains in a stationary position with the Woven goods passing through it and is actuated by movement of the lay bar. By this arrangement the woven goods may be easily moved between rollers of the temple and the temple maintained in its proper operative relationA to the selvage edge of the goods and have operative movement imparted to its clipping mechanism each time thek lay bar is swung towards the temple.

Another objectof the invention is -to provide the temple with selvage-engaging rollers of such construction that the fabric will pass between the rollers without being damaged thereby and held in a taut condition so that the cutting mechanism may engage and easily sever threads projecting from the selvage edge.

It is another object of the invention to provide the temple with thread-clipping mechanism of such construction that, when an actuating member thereof is engaged by the lay bar, threads to be cut will be caught by a ringer of the clipping mechanism and drawn into engagement with a cutting knife. n

It is another object of the invention to provide a temple including a portion adapted to be iirmly secured to the frame of the loom and a companion portion which is pivoted to the mounting portion but yieldably held in an upright position until the cutting mechanismis engaged by the lay of the loom. It willthus be seen that, while the cutting mechanism may be operated by the lay, the member carrying the cutting mechanism will be permitted to yield during operation of the cutter by the lay beam and thus prevent damage to the loom due to restricted movement of the lay beam. l

The invention is illustrated in the accompanying drawings, wherein A Figure 1 is a -view showing the improved temple mounted in position for use, the view being principally in side elevation `but having portions A shown inl section,

Figure 2 is a view in elevation looking from the right in Figure 1,

Figure 3 is a top plan view of the improved temple with a portion broken away, Figure 4 is a sectional view taken through the 5 thread-clipping mechanism, the View being along the line 4 4 of Figure 3, and

Figure 5 is a sectional view taken along the line 5-5 of Figure 3. The selvage-clipping temple constituting the 10 subject-matter of this invention is secured to a side portion of the frame of a loom, and in Figure 1, a portion of the frame, which is indicated by the numeral I, has vbeen shown with certain elements of the loom secured thereto. 15 There has also been shown the lower take-up roll 2 and the supporting bar 3 therefor. The temple extends vertically at a side of the loom, and in order to mount the temple upon the frame I, there has been provided a bracket #l which is 2O formed of strong cast metal and provided with a vertically extending slot 5 through which a bolt 6 passes so that the bracket may be shifted vertically to adjust the position of the temple and the bolt then tightened to securely hold the 25 bracket in the adjusted position. A flange 'I projects outwardly from the frame-engaging portion of the bracket and along its free side edge is formed with a lip 8 so that, when a mountingv member or bar 9 has its lower portion disposed 30 against the flange 'I between the attaching portion of the bracket and the lip 8 and a securing bolt I0 is passed through registering openings formed in the flange and the lower portion of the mounting bar, the bar will be securely held in place and prevented from turning about the bolt out of a vertical position. Y

The mounting bar 9 is formed of channel metal in order to provide side flanges II, and upon referring to Figures 1 and 2, it will be seen that slightly above the upper end of the bracket 4 the side Ilanges have been externally thickened and extended to form bearings I2 to receive a pivot pin or bolt I3 which extends through a hinge ear or bearing I4 formed at the lower end 45 of a shank or bar I5. The shank or vbar I5 is" also formed of channel metal to provide side flanges I 6 and the channeled portion of the shank is of such Width that it will fit snugly between the ilanges of the mounting bar 9. An opening I 1 is formed through the shank, as shown in Figure ".1, and freely receives a stem or pin I8 which has one end screwed intoa threaded opening I9 formed in the bar 9.- A helical spring 2D( surrounds the portionof the pin or stem Which pro- 55 jects from the shank and has its inner end bearing against the shank between the flanges I6 thereof and its outer end in abutting engagement with a washer 2| which iits about the threaded outer end portion of the stem and is held in place by a nut E2. By adjusting the nut the tension of the spring 255 may be adjusted and the ease with which the shank may be swung about the pin or bolt I3 away from the mounting bar 9 controlled.

Under normal condition, the shank will be refro tained in anupright position, but during a cutting operation the shank may be swung away from the mounting bar so that moving portions of the loom will not be unduly interfered with and breakage of parts caused. Shoulders 23 are formed at opposite sides of the shank adjacent upper ends of the flanges I6 to overlie upper ends of the flanges l l of the mounting bar 9 when the shank is in its upright position, and upon referring to Figure 2, it will be seen that the upper portion 24- of the shank is of greater width than the lower portion. This upper portion of the shank is not provided with side flanges and is bent intermediate its length, as shown at 25, in order to impart added strength to the upper portion of the shank. At its upper end the shank terminates in a head 25 from which extends a side arm 21, and it should be noted that this arm is formed with a slot 28 which extends longitudinally of the arm between depending flanges 29 formed along side portions of the arm. The depending marginal flanges serve to strengthen the `arm and also constitute means for securing nuts upon bolts which pass through the slot of the arm, as will be hereinafter brought out.

Upper and lower roller housings 3D and 3l which are also formed o-f cast metal are disposed in front of the side arm substantially parallel to but in a higher plane than this arm, and in these housings are rotatably mounted rollers 32 and 33, The upper roller is preferably formed of wood and rotatably supported in its housing by a rod or axle 34 formed as an elongated bolt which is passed through the head 35 at the outer end of the upper roller housing and has its inner end screwed into a threaded opening formed in the inner end wall or head 3.6 of the housing. The inner end wall of the upper housing is extended lto form a plate 531 and side varm 36 for the housing, and in order to mount the upper roller housing, there has been provided a flange 39 which extends transversely from the plate and side arm and has overlapping fengagement with a mounting plate 40 carried by an arm 4| projecting rearwardly from the lower roller housing. Registering openings are formed in the flange 39 and vmounting plate 4U to 'receive the securing screw or bolt 42 and the plate is also formed with slots 43 to receive 'belts 44. These bolts 44 extend through the slot 28 of the side arm 21 and the nuts 45 of the bolts are `disposed between the depending flanges 29 which prevent rotation of the nuts about the bolts and thus prevent the nuts from working loose from the bolts. The plate 4D is of less thickness than the arm 4i carrying the same, thereby providing the arm with a shoulder 46 at its vend against which the front end 'of `the flange 39 abuts. Tt will thus be -seen that, when the flange `39 is applied to the plate with the innerend of the flange engaging the rear shoulder 'of the arm 4I, the upper` and lower roller housings will be heldin proper relation to each vother and lmaintained substantially parallel. The lower rollery 3T3 is preferably formed of rubber and is carried 'byan and lower rollers,

an inverted U-shape.

axle 41 which is also in the form of an elongated bolt passed through the outer head 4S of the lower roller housing and screwed into a threaded opening formed in the inner head 49 of the lower housing.- A strip of metal is wound spirally about the upper roller to form a metal sheathing 50 for the wooden roller, and upon referring particularly to Figures 3 and 5, it will be seen that this metal sheathing is punched to provide outstanding teeth or spurs, which grip the side edge portion of the woven material 52 and cause the material to be fed smoothly between the upper In View of the fact that the lower roller is formed of rubber, it will have good frictional engagement with the woven material but at the same time it will be suiciently yieldable to prevent the material from being marked lor otherwise marred by the spurs of the upper roller.

VDuring feeding of the woven fabric between the rollers, it is desired to have thread 53 projecting from the selvage edge of the fabric chipped off. In order to do so, there has been provided cutting mechanism enclosed in a housing 54 mounted against the outer side face of the plate 31 and side arm of the upper roller housing. The housing 54 for the cutting mechanism is formed of metal and has inwardly projecting ilanges 55 and 56., openings 51 being formed through the lower flange to receive securing screws or bolts 58 which are screwed into threaded openings 59 formed in the plate 31 to securely but detachably hold the housing 54 in place. The cutter housing is open at its front and rear ends and in this housing is mounted a grapple 60 which is vformed of strong metal and at its rear `end is formed with a bill or hook 6I. A cutting blade 62 which conforms to the outline of the hooked end of the grapple `is secured against the inner side face thereof by screws or equivalent fasteners 153. This blade is in .confronting relation to a companion stationary blade 64 which is secured against the end plate 31 of the upper roller housing by a removable fastener 65, and it will be readily appreciated that, vwhen a thread 53 is engaged by 'the `bill or hook 6l of the grapple and drawn -into vthe cutter housing through the open front -end thereof, the thread will be severed by the two cutter plates or blades 62 and 64. The inner or rear end portion of the i grapple is extended downwardly to form a shank -or arm 66 which projects through an opening vformed through the bottom and rear end `of the housing, and this a-rm or shank has its lower end portion for-med with a depending finger or trigger 61 terminating vat its lower end i-n an enlarged head `-68 through which a -bolt 69 is passed. A

'side extension for shoulder 10 is formed at one side of the lower end of the arm 66 which is disposed under the cutter housing and limits upward and rearward movement of the grapple by engagement Awith the lower edge face of the cutter housing.Y While the grapple is lloose in the housing, its movement must be controlled, and in order to do so, there has `been provided a spring 1I formed from a strip of Yresilient metal bent to One rarm 12 of the spring extends downwardly from the bridge portion thereof between the pin 13 and the Aanchoring screw or Abolt 14 and formed with Van eye through which the bolt 14 passes to rmly hold the spring in place. The other arm 15 `of the spring is of greater length than the arm 12 and extends downwardly from fthe vcutter housing and terminates in a bent lower end providing a tooth 16 which is selectively engaged in one of a series of notches or seats 'Il formed in the rear face of the finger or trigger Bl. The spring exerts forward and upward thrust upon the trigger of the grapple and normally maintains the grapple in the position shown in full lines in Figure 4. When, however, pressure is applied by engagement of the lay bar 18 with the headed forward end of the bolt or adjustable abutment 69, the grapple will l'lrst be tilted to swing the hook or bill 6 I downwardly into engagement wtih a thread 53 and as the side extension or abutment flange 10 moves rearwardly and upwardly into flat contacting engagement with the lower edge of the cutter housing further pressure by the lay bar will cause the grapple to be shifted rearwardly and draw the hook 6l inwardly to cause the thread to be cut by the cooperating blades 62 and 64. When the grapple is tilted by initial pressure of the lay bar, the lower edge face 19 of the grapple will be brought into flat contacting engagement with the upper edge face of the flange 56 of the grapple housing, as indicated by dotted lines in Figure 4, and this will aid in guiding rearward shifting of the grapple. Engagement of the arm 15 of the spring with the front side face of the arm 21 limits rearward movement of the grapple, but if the lay bar continues its movement in this direction, the shank or bar l may tilt rearwardly about its pivot pin I3 and this will prevent breakage of parts of the loom..

When the lay bar moves forwardly away from the temple, the spring 20 will return the shank to the upright position and the spring 1I will return the grapple to the position, as shown in full lines in Figure 4. Movement is imparted to the grapple each time the lay bar moves forwardly andV all thread which projects from the selvage edge of the fabric will be clipped. If it is found that the trimming mechanism and the rollers do not have proper engagement with the marginal portion of the woven fabric, it is merely necessary to loosen the bolts 44 yand adjust the same either longitudinally of the arm 2lY 'or transversely thereof and then again tighten the bolts. By shifting the grapple in the cutter housing to move the nger 'I6 of the spring arm from an upper notch 11 into -a lower notch the extent of tilting movement imparted to the grapple may be reduced and by moving the tooth to the lowest one of these notches tilting movement of the grapple may be entirely eliminated. Rearward shifting of the grapple will, however, at all times be permitted.
